Definitions
- the present invention relates to shoes, particularly to a sole capable of providing an effective ventilation and massage of the user's foot during walking.
- moulded soles for shoes comprising resilient chambers located both on the upper surface of the sole so as to contact the insole underneath the foot and projecting downwards from the sole so as to act as a tread.
- Such chambers are indeed air chambers communicating with the inside of the shoe and allowing the foot to be more or less effectively ventilated during walking in order to oppose to the troublesome, not very hygienic perspiration of the foot. They also provide a more or less strong cushioning effect because of their deflection and expansion back to their original state during walking.
- the present invention seeks to overcome the above problems and provides a shoe sole of the above-mentioned type in which the arrangement of the air chambers is not limited to the upper or lower side of the sole anymore but takes up the whole thickness of the sole, thus also ensuring an effective shock-resistant action against any soil unevenness on which the foot is laid besides enough ventilation to the benefit of the user's foot.
- a second object of the present invention is to provide a sole of the above-mentioned type wherein the air chambers are provided with means capable of exerting a beneficial, tonic action causing the user's feet to be massaged in a more significant manner than heretofore known.
- Still another object of the invention is to provide a particularly light, cost-effective shoe sole of simple, sturdy construction being affected by no problems caused by any of its mechanical parts and/or delicate components.
- Another object of the invention is to provide a shoe sole wherein the tread is capable of expelling any material stuck on it during walking.
- a sole which comprises a plurality of air chambers or hollow spacers generally hemispherically shaped and with a circular plan extending under the sole and forming the tread to replace the common spacing reticulated pattern on the upper side of the sole.
- the shape of a single spacer is similar to that of an igloo with a central hole at the top.
- a little member projecting towards such central hole and capable of plugging the same during the deflection is provided inside each igloo.
- the form of the “igloo”-shaped spacers having a thickness gradually decreasing towards their upper portion as well as the selection of materials capable of being resiliently deformed is such as to create an air circulation with air change under the user's foot sole during walking.
- the sole's performance as it was described so far may be summarized as follows: the movement during walking with repeated cycles of the user's weight loading onto and unloading from the foot sole is used to create an air circulation under the foot. In fact each single igloo exerts a pumping action due to its resilient deformation. During the user's weight loading step, the igloos deflect and deform and their reduction in volume causes the air contained therein to be forcibly expelled through the upper hole.
- the consequent resilient return causes an air suction with the ensuing filling of the igloos with the air from the shoe.
- the air circulation is not limited to an expulsion and a suction of the same air to the detriment of a real air change.
- the lower surface of a fixed insole rests on the igloos so as to form a valve which causes, in the expulsion step, the air pressure to push the edge of the upper holes against the fixed insole preventing the air from escaping sideways and forcing the same to reach the inside of the shoe and the user's foot.
- air is prevented from lingering in the gaps among the igloos.
- the transpiring frame of the fixed insole once expelled the air is conveyed through the transpiring frame of the fixed insole.
- the shape and the thinness of the edge or lip of the upper holes of the igloos allow fresh air to enter the latter through the openings in the vamp that communicates with the outside.
- Another advantage of the invention is that the igloos provide a pleasant, effective massage to the sole of the foot so that blood circulation results to be improved.
- FIG. 1 is a partially sectioned side view of a shoe without a sole
- FIG. 2 is a cross section of a first embodiment of the sole according to the invention.
- FIG. 3 shows a detail of the sole of FIG. 2
- FIGS. 4-5 and 6 - 7 similar to the preceding FIGS. 2 and 3 show a second and a third embodiments of the invention, respectively;
- FIG. 8 is a cross section of a fourth embodiment of the sole according to the invention.
- the sole according to the invention is capable of being applied to a winter or summer shoe A, with or without shoestrings which may also be a boot or a sandal provided with a fixed insole B having a series of holes.
- Such fixed insole B is covered with a so-called cleaning sole C which is perforated.
- the air blown in by the sole during walking can flow through the perforation so as to easily reach the inside of the shoe.
- the sole according to the invention essentially consists of a peripheral rib 14 and a tread 10 .
- the vamp is anchored to said rib 14 by conventional gluing and, if necessary, a sewing.
- the tread includes a number of air chambers which also monolithically extend towards the upper portion of the sole, i.e. that portion on which the perforated fixed insole of the shoe rests.
- Each air chamber hereafter called “igloo”, has a tread 10 provided with a central portion 7 shaped as a suction cup. Obviously, such a shape is not the only possible form of that portion as the tread may show different patterns in order to have an antislip function.
- the igloos are structurally bound to one another to form the sole by dint of support members 4 .
- the sole in top plan view shows a series of half-spheres 2 provided with holes 1 at their upper side.
- the half-spheres exert a massaging action and at the same time blow air in.
- a large amount of air is blown into the air chambers or igloos as the latter have a remarkable volume 9 as a consequence of their lower walls 5 of small thickness resting directly on the ground and acting as a tread.
- Such “igloos” give a considerable comfort to the foot which always rests on a pleasantly soft surface.
- each protrusion 6 projecting from the base of each igloo towards their respective upper hole 1 .
- each protrusion 6 will occlude the corresponding hole 1 before all of the air in cavity 9 of the igloo escapes.
- each igloo acts as an airtight hollow body in which the air is the cushioning resilient element.
- the operation has a number of steps: one step of soft deflection with simultaneous air blowing into the shoe, a following airtight sealing before the air chambers have been completely emptied, the ensuing resilient cushioning shock-resistant effect, and the subsequent filling after the user's weight has been unloaded and the air sucked through the gaps among the igloos with consequent air circulation during walking.
- FIG. 2 also shows upper surface 3 of the sole as well as surface 11 to which the vamp is glued and groove 13 in which the sewing is made.
- FIGS. 4 and 5 in which the construction components corresponding to those already described are designated by the same numerals as those used in FIGS. 2 and 3 with the addition of a prime, the operation is quite similar to that already described above. Even if such a second embodiment bears features found in the first embodiment, it provides igloo-shaped air chambers having a hemispheric upper portion which is wholly located under upper surface 3 ′ of the sole.
- the deflection of the igloos by the user's weight causes air to be blown into the shoe and holes 1 ′ to be then occluded by members 6 ′ so that residual air in cavity 9 ′ is caused to provide the already described resilient shock-resistant action.
- the projecting members 6 ′ have a different form from that of members 6 of the preceding embodiment as they have a tapered, roundish point 16 at the top of an offset 15 . Such an offset aims at occluding holes 1 ′ during the deflection caused by the user's weight on walking in order to produce the already described shock-resistant effect.
- roundish point 16 of member 6 ′ has a diameter which is shorter than that of hole 1 ′ and such a height as to slightly project from upper surface 3 ′ of the sole when the igloo is deflected and offset 15 occludes hole 1 ′.
- member 16 projecting from surface 3 ′ softly strains the lower surface of cleaning sole C of the shoe producing a massaging effect which considerably improves blood circulation of the foot.
- a third embodiment of the invention shown in FIGS. 6 and 7 has essentially the same features as the preceding embodiments but is simplified as it does not provide any member corresponding to member 6 or 6 ′ capable of occluding hole 1 or 1 ′ during walking.
- the shock-resistant function is only accomplished by the resilient deformation of the igloos that make up the sole.
- FIG. 8 A further and last embodiment of the sole according to the invention is illustrated in FIG. 8 and envisages igloos having a common lower portion which forms tread 10 ′ and coincides with support members 4 ′ joining said igloos to one another.
- igloos having different shapes and/or volumes and/or heights may be advantageously provided in order to satisfy the most diverse technical and/or aesthetic requirements.
- still another advantage of the invention is that the air chambers formed by the igloos perform an insulating action keeping the inner temperature of the shoe close to that of the body.
- the sole according to the invention described can be produced in just one moulding step by using resilient material of different kinds capable of being deformed and recovering their original shape immediately after the deformation.
- Said materials are preferably resistant to abrasions, ultraviolet rays and low temperatures.
- igloo-shaped members are built-up parts and not integral with the remainder of the sole.
- igloos may be formed by materials having specific weight greater than the remainder of the sole.
